WRAPPER CARRIER FOR CIGAR MACHINES.

Application filed October 28, 1921.

To all whom it may ooncem:

Be it known that I, RUPERT E. RUNDELL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in \Vrapper Carriers for Cigar Machines, of which the following is a specification.

This invention relates to an im rovement in wrapper carriers for cigar mac ines, and it has for its main object the production of a device of this general character having an increased range of usefulness in that, in conjunction with a wrapping mechanism, it can automatically wrap cigar bunches of sizes and shapes which heretofore could not be wrapped by machine. A further object of the invention is the production of an improved device for transferring oneend of a '20 wrapper from a wrapper support to a cigar bunch in a wrapping mechanism, which device is more economical and more efficient. With these and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying drawings, which form a part of this specification and in which like characters of reference indicate the same or like parts, Fig. 1 is a plan view of a device constructed in accordance with the invention; Fig. 2 is a side elevation of a part of the structure shown in Fig. 1, but shown on an enlarged scale and partly in section; Fig. 3 is a detailed view, as seen from the right end of the machine, showing theblower illustrated in Figs. 1 and 2 but on an enlarged scale and partly in section; and Fig.4 is a view of the same blower as seen from the front of the machine when in a difierent position.

In carrying the invention into effect, there is provided a wrapper support, a blower or blast mechanism mounted on said support, and blower controlling means. In the best constructions, there is further provided a standard, an oscillatory support pivoted to said standard, a relatively long reach arm one end of which is pivoted to said supporting arm, a wrapper support pivoted to the opposite end of said reach arm, means acting on said reach arm between its ends to Serial No. 511,165.

swing it on said supporting arm, and means acting on said wrapper support approximately in its median plane to swing it on said reach arm. All of the above mentioned parts may be widely varied in construction within the scope of the claims, for the particular device selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the precise details of the structure shown and described.

Referring to thedrawings, 5 indicates the bed of a cigar machine of well known type. Suitably supported by a frame rising from the bed 5, but not shown in the drawings, is

a wrapping mechanism 6 also of well known type.

The machine in connection with which the present invention is used is further provided with a cam shaft 7 carrying a cam drum 8 having a cam groove 9 cut in its periphery. Tracking in this cam groove is a bowl 10 carried y one end of a lever 11 fulcrumed at 12 to a bracket rising from the bed 5. The opposite end of the lever 11 is in the form of a sector gear 13 which meshes with a sector pinion 14 fast to an oscillating post 15 journaled in a standard 16 rising from the bed 5. The post 15 is hollow and its upper end is closed by means of a plug 17. Its lower end is provided with suitable suction producing mechanism, not shown but well known in the art. Fixed to the upper end of the post 15 is a hollow supporting arm 18 formed integrally with an arm 19, both arms bein of course pivoted on the standard 16. onnected with the supporting arm 18 is a hollow reach arm 20, one end of which is pivoted to the supporting arm at 21. To the opposite end of the reach arm 20 is pivoted a hollow wrapper support 22. By an inspection of Fig. 2, it will be readily understood that the standard, sup porting arm, the reach arm, and the wrapper support arein intercommunication for the purpose of establishing suction in thewrapper support 22. The structure so far described is broadly old and well known and a more detailed description thereof, being unnecessary to a full understanding of the present invention, is omitted in the interest of brevity and clearness.

The means whereby the wrapper support sari'ly wrappe new arrangement of wrapper carrier parts bein is given its wrapper delivering movement is however difl'erent from similar devices heretofore known in order that machines equipped with the present device may produce effects heretofore found impossible of accomplishment. With this end in view, the arm 19 carriesa cam bracket 23 provided with a bowl 24 tracking in a cam groove 25 formed in a stationary cam plate 26 suitably supported from the bed 5 by supports, not shown but of well known character. The free. end of the cam bracket 23 is pivotally connected to one end of a link 27, the opposite end ofsaid link being pivoted to an arm 28 cast on the reach arm 20 before referred to. This cam actuated link mechanism acts on the reach arm 20 between its ends.

The arm 19 further carries a cam bracket 29 provided with a bowl 30 tracking in a cam groove 31 cut in the cam plate 26 before referred to. The free end of the cam bracket 29 is pivotally connected to one end of a link 31, the other end of said link being connected to an arm 32 extending from the wrapper support 22 before referred to.. The median plane of the wrapper support 22 is indicated in Fig. 1 by the broken line 'MP. The cam actuated link mechanism just described acts upon the wrapper support in or approximately in its median plane.

As aresult of the structure so far described, the wrapper support 22 is given a movement which is the resultant of an approaching movement controlled by the cam groove 9, a traversing movement-controlled by the cam groove 25, and an angular movement controlled by the cam groove 31, this resultant movement having a greatly increased range which enables it to properly deliver a wrapper to an extremely long and blunt ended ci ar bunch heretofore necesby hand. Moreover, the

makes possible the use of cams more nearly approaching true arcs, thus decreasing wear and increasing durability.

As usual, a Wrapper is held on the lower surface of the wrapper support 22 by suction, and as usual one end of the wrapper is blown from the wrapper support by a blast of air. The means employed for producing this blast of air, is, however, materiall different from that heretofore used, the c ange made to overcome defects of the blowing evices heretofore used and in the interest of economy. With this end in view, there is mounted on the wrapper support 22 a blower 33 cylindrical in form and having an opening 34 in its lower head which establishes communication between the interior of the blower and the interior of the we per support at one end of the latter. In the present construction, a blower is used discs 35 and 36, and a leather cup 37 between said discs, the whole being held on a stem 38 by means of a nut 39. The stem 38 projects through the upper head 40 of the blower and carries at its upper end a discal head 41 held on the stem by means of a nut 42. Surrounding the stem 38 is a spring 43 one end of which bears against the head 40 and the other against the disc 36 of the plunger, the function 'of this spring being to force the plunger down into the blower and expel the air below it through the openin 34 and the perforations in the lower face of the wrappersupport 22 immediately below said opening. The head 40 is provided with a vent 44 through which air idly flows when the plunger is in operation,

The blower is used only at one point in the cycle of machine operations, and blower form of a lever fulcrumed on a stud 46 fastin a lug 47 projecting from the blower head 40. Coiled around the stud 46 is a torsion spring 48, the purpose of which is to normally hold the upper end of the detent 45 in toward the axis of the blower. The upper end of the detent is provided with a notch 49 adapted to engage and hold the discal head 41 when the latter is brought into register with it.

For the purpose of bringing the discal head 41 into register with the notch 49 of the detent 45, thereby compressing the spring 43 and setting the blower plunger, there is provided an arm 50 secured to a reciprocating rod 51, this being the rod which operates the device whereby paste is applied to a wrapper on the wrapper support when the latter is in its rearmost position and the wrapping operation is about to begin. This paste applying device is well known. Briefly, it consists of a paste carrier 52 normally submerged in the contents of a paste pot 53 but lifted therefrom to apply the paste to a wrapper on the wrapper support. The paste carrier 52 is mounted on an arm 54 carried by the reciprocating rod 51, the reciprocation of which is effected by means of an arm 55 fixed on a short shaft 56 which also carries an arm 57 connected to a forked link 58 carrying a cam bowl 59tracking on a cam 60 fast on the shaft 7 before referred to. It will of course be understood that the wrapper support picks up a wrapper in the wrapper cutting position indicated at 61 in Fig. 1, and that as soon as the wrapper is picked up the wrapper support is moved to a position wholly to the rear of the wrapping mechanism 6, where its rear end 'comes immediately over the paste carrier 52. As it comes into this position, the head 41 moves over the end of the arm 50 and when the rod 51 is given its upward movement to apply paste to the wrapper on the support, the head 41 is moved upward from the position shown in full lines in Fig. 4 t0 the position shown in dotted lines. When it reaches this position, the notch 49 of the detent 45 engages the head 41 and holds it in its uppermost position when the wrapper support moves away from the arm 50 with the blower plunger set for action.

Means are provided for releasing the plunger at the proper time, in the present instance near the end of the wrapping op eration, and where the flag of the wrapper is to be blown from the wrapper support to the tension plate of the wrapping mechanism. As shown, this means consists in a stud 62 screwed into anarm 63 forming a part of the frame of the wrapping mechanism 6. The stud 62, like the arm 50, is in the path of movement of the wrapper support so that when the support reaches the proper position, the lower end of the detent 45 comes into engagement with the stud and a slight further movement of the support causes the detent to rock on its fulcrum and throw its notch 49 out of engagement with the stem head 41, thereby releasing the plunger and permitting the spring 43 to force it downwardly into the blower and expel the air therefrom. It has been found that a small blower traveling with a wrapper support and having short air passages is more economical and more eiiicient than the devices heretofore known wherein larger blowers were necessarily located at a distant point andthere was a loss of efliciency due to the long air passages.

In view of the foregoing, a detailed description of the operation ofthe structure shown is deemed unnecessary and is therefore omitted in the interest of brevity.
